Sony is expected to unveil its much talked about attachable smartphone lens cameras, the DSC-QX10 and DSC-QX100 alongside the long-rumoured flagship smartphone, the Xperia Z1 on September 4 ahead of the IFA.

A fresh rumour claims that the attachable smartphone lens cameras manufactured by Sony will be dubbed as 'Smart Shot'. SonyAlphaRumors cites its sources to claim that the lens camera will be officially known as Smart Shot which is a mix of Smart-phone and Cyber-Shot.

The site also reveals that the Smart Shot lenses will come with lens stabilization, record full-HD videos with MP4 format and even record videos in low light conditions with low noise. The Smart Shot lens cameras are said to be compatible with all Android and iOS devices, as reported earlier. The captured images will automatically be saved in both the lens camera memory card and the smartphone.

The site also notes that the QX10 will have the same 1/2,3-inch with 18-megapixel CMOS sensor and f/3,3-5.9 lens which is found in the Sony WX150 camera and will probably be priced at $250 while the QX100 is said to be priced at $450.
